FREDRIO C.`WEIR, OF CIN IMPROVEMENT IN RAI LROA'D-FROGS.

` Specification forming part of Letters Patent No. 215.5118, dated May 20, 1879; application filed February 4, 1879.

To 'cll'whom t may concern Be it known that I, FRnDRIc C. WEIR, of Cincinnati, Hamilton county, State of Ohio, have invented an Improvement in Railroad Frogs, of which the following is a specification.

My invention relates to the class of frogs made by the bending of the overlapping' ends of the rails themselves and the junction of the same with the central rails constituting the point by rivets or bolts through separatingpieces; and my invention consists, irst, in such a formation and connection of the two rails which make up the .ngular point as that one of the :railsextends unbroken and uncut directly across the path of the other, and in itself makes a solid end to the point, with a full-width flange, which is overlapped by the ange of the other rail, and thus a lange of double thickness is afforded at a point where strength is particularly needed, and the cutting away of the flanges (as is the usual custom) avoided entirely; second, in an improved manner of connecting the two rails of the point together, and to angle or channel iron pieces, to which the outer rails are connected.

In the accompanying drawings, Figure lis a plan of a frog embodying my improvements. Fig. 2 is a cross-section ofthe same on line a'. Fig. 3 is a plan of the under side of the frog, showing the continuation of the main point-rail with a full width of iiange throughout. Fig. 4 is a plan of the frog, embracing a modification inthe manner of connecting the rails, Fig. 5 being' a cross-section of this iigure.

A A' are the outer or wing rails of the frog, and B B' are the two rails which compose the acute angle or point. In place of cutting away both the iianges of the rails B B', so as to make a joint between the two rails midway between the lines of the angle of the frog, as is common now, and I may say universally practiced, I continue the ilange b of rail B, of full width, intact clearalong the junction of the-two rails to the point where it strikes the ange of the outer rail, as shown in Fig. 8, which is almost immediately under the point rv' of the frog, and I swage up the flange b of rail B' on one side, as shown in Figs.` 2 and 3, so thatit lies over the iiange of rail B, this flan ge of rail B' being cut away angnlarly on the edge to properly meet the line of the web b" of the rail B.

I connect the point-rails B B' together by rivets C, which, whilethey secure these rails together, also secure pieces of angle or channel iron D to said point-rails, the channel or angle iron making the separating medium. between the points-rails B B' and win g-rails A. A', an d giving a means for attaching said wingrails.

Withchannel-iron I attach the wing-rails in the manner shown in Fig.' 5, the outer flanges of the iron being notched at d for the passage, before the outer rails are attached, of the long rivets C, the bolts E, which connect the outer rails, being placed between the notches d.

With angle-iron I use a bottom plate, F, as shown in Figs. l and 2, which has turned edges f, and, when slid on and driven into place endwise on the frog, is secured by rivets G. Whether it be angle-iron or channel-iron, I extend it beyond the point so as to make ears I-I, which I join by a bolt or rivet, I, which serves to materially strengthen the point.

I claiml. A frog having one of its point-rails eX- tending with a full-width flange along the junction of the two rails, and the flange of' the other point-rail overlying the an ge of the rst-mentioned one, substantially as and for the purpose specified.

2. In combination with the poin t-rails B B', itted to each other as described, the angle or channel pieces D, extending and bolted or riveted together beyond thepoint of the frog, and connecting-rivets (l, which extend entirely through the two point-rails and the angle or channel pieces, substantially as and for the purpose specified.

\ In testimony of which invention I hereunto set my hand.
